以下参照图7和8描述成员100再现数字内容的步骤。 The following steps 7 and 8 members reproducing digital contents 100 will be described.

在再现租用的数字内容时,首先接通(S31)计算机110,然后调定(S32)再现软件。 When reproducing the digital content rented first turned (S31) the computer 110, then it is set (S32) playback software. 在调定再现软件时,运用配置在再现软件里的测量程序,通过观看成员100计算机110中内置的实际定时时钟,确认(S33)上述时限周期是否超过。 When it is set in the reproduction software program measured using the configuration software in the reproduction, by viewing the member 100 built in the computer 110 the actual timing clock confirmed (S33) exceeds the above-mentioned time period. 另外,实际定时时钟由计算机110的内置锂电池等内部电源操纵,因而即使关掉计算机110的主开关,仍能继续操纵当前时间。 Further, the actual timing of the clock built into the computer operated by the internal power source 110 is a lithium battery and the like, even if the main switch to turn off the computer 110, can continue to manipulate the current time.

若上述时限未过,断定在租期内,就可再现(S34)该数字内容。 If the above time is not over, we concluded that the lease term, can reproduce (S34) the digital content. 点击图8(A)中屏700A里的再现钮710A,开始再现。 Click FIG. 8 (A) in the screen 700A in the reproduction button 710A, a reproduction start. 另外,若不再现数字内容时,就点击重置钮720A。 In addition, if the time of reproducing digital content, click on the reset button 720A. 而且,在再现数字内容时,在屏下部示出停止、暂停、反转、快进等钮。 Further, when the digital content is reproduced in the lower portion of the screen shown stop, pause, reverse, fast-forward button.

在过了上述时限的情况下,判定租期结束,再现软件可用删除程序删除(S35)录制的数字内容,并在成员100计算机110的显示器上示出图8(B)的屏700B。 In the past the above time limits, determining the end of the rental period, the digital content can be used to delete the reproduction program deletes (S35) the recording software and shown in FIG. 8 (B) on the display screen 700B member 100 of the computer 110. 该屏700B示出一条消息,如“租期已过,将从硬盘里删除数字内容”。 The screen 700B shows a message such as "lease has expired, delete digital content from the hard drive." 这样,一系列租用和再现步骤结束。 In this way, a series of rental and reproduction step ends.

根据上述实施例,虽然在断定删除数字内容时应用了租期的概念,但是也可应用再现次数的概念。 According to the above embodiment, although the concept applied in determining the lease deleting the digital content, but may also be applied to the concept of reproduction times. 例如,成员100在租用数字内容时预先设定可再现次数,计数再现软件再现数字内容的次数(已再现的次数),并将可再现次数与已再现次数作一比较。 For example, the members 100 may be set in advance when reproducing the digital content rental times, the number of times the digital content reproducing software (already reproduced number of times) the reproduction count, and the number of reproducible times has been reproduced with a comparison. 当已再现次数超过可再现次数时,断定租期结束,删除贮存在硬盘里的数字内容,并示出一消息,如“可再现次数已过,删除硬盘里的数字内容”。 When playback has exceeded the number of reproducible times, the lease ends concluded, deleting stored in the hard disk of the digital content, and shows a message such as "the number of reproducible elapsed, remove the hard disk of the digital content."

此外,删除程序可以改写至少一部分存贮的数字内容,从而不被再现软件再现。 In addition, the program can be rewritten to delete at least a portion of digital content stored so as not to be reproduced playback software.

再者,可以结合使用租期和可再现次数的概念,此时,任一概念结束时,都可删除硬盘里贮存的数字内容。 Further, the concepts can be used in conjunction with the lease of the reproduction times and, at this time, at the end of any one concept, the digital content can remove the hard disk storage.

另外,虽然在上述描述中的调定再现软件时断定租期等是否已过,但是也可在接通成员100计算机的主开关时作判断。 Further, when judged in the above description, although it is set in the reproduction software and whether the lease has expired, but may also be determined in the computer 100 when the main switch is turned members.

同时,在上面描述中,虽然要租用的数字内容的数量为1,但是可以同时租用多种数字内容,此时可对每种数字内容设定租期(可再现次数),在准备再现数字内容时,可判断要再现的数字内容的租期是否过了。 Meanwhile, in the above description, although the number of the digital content to be leased is one, but a variety of digital content can be rented at the same time, this time can be set for each term of the digital content (reproducible times), in preparation for reproduction of the digital content , the lease may determine whether the digital content to be reproduced before.

另外,在上面描述中,虽然再现软件通过电话线400从出租商200装入成员100的计算机110,但是也可运用CD-ROM或软盘等记录媒体安装。 Further, in the above description, although the reproduction software 400 loaded into computer 110 from the rental store member 100 via a telephone line 200, but may also use a flexible disk like CD-ROM or a recording medium installed. 此时,再现软件可以免费分发,例如作为某种杂志的补充,而该杂志对本发明数字内容租用方法的推广使用作出了巨大贡献。 In this case, the reproduction software can be distributed free of charge, for example, as a supplement to a certain magazine, and the magazine made a great contribution to promoting the use of digital content to rent the method of the present invention. 此时,登录为成员的方法可用电话线在线实现,或向出租商邮寄数据输入表作离线实现而不用电话线。 In this case, log on as a member of telephone lines available methods to achieve online, or by mail to the lessors for offline data entry form to achieve without a telephone line.

另外,在上面描述中,虽然成员100计算机110是普通的个人计算机,但是对数字内容租用方法而言,可以是一种专用再现装置。 Further, in the above description, although the members of the computer 100 is a general personal computer 110, but the method for renting the digital contents, may be a dedicated reproducing apparatus.

再者,由于贮存在出租商200存储器220里的曾出租的数字内容信息作为成员的信息,所以查看该信息可以分析成员100的爱好。 Furthermore, since the digital content stored in the memory 220 in 200 rental providers had rented a member information as the information, so the information can be analyzed to see loving member 100. 这样,当把断定迎合成员爱好的新内容录制在服务器210里时,可将该信息以电子邮件发给该成员。 Thus, when the judge cater to new members interested in the content recording server 210 where the information can be e-mailed to the member. 而且,成员可预先登录其爱好。 Also, members can pre-register their hobby.

在上面描述中,虽然把影片用作数字内容的实例,但是数字内容可以包括乐曲、电视游戏软件或计算机应用软件等概念。 In the above description, although the movie is used as an example of digital content, but the concept of digital content can include music, video games, computer software or application software.

另外,由于详述的步骤是一例本发明的数字内容租用方法,所以操作步骤并不限于此,可以改变诸步骤的顺序,也可改变屏幕。 Further, since the step is detailed example of a method of digital content renting the invention, the procedure is not limited thereto, you can change the order of various steps may also vary screen.

还有,在上述实施例中,虽然把数字内容信息贮存在用户成员100计算机110的硬盘内作为一种信息,但是也可把它分开来存贮。 Further, in the above embodiment, although the digital contents information stored in the hard disk of the user computer 110 member 100 as an information, but it may also be stored separately. 此时除了再现程序、测量程序(计数程序)和删除程序以外,上述的再现软件要求包含将下载的数字内容分为多个部分的划分程序、对划分程序划分的数字内容加密的加密程序、以及对加密程序加密的数字内容解密并且联合再现划分的数字内容的解密与再现程序。 At this time, in addition to the reproduction program, the measurement program (program counter), and delete program, and the reproduction of the digital content comprises software required to download the program is divided into a plurality of portions, for dividing the digital content encryption program into encrypted program, and encrypted program and decrypting the encrypted digital content reproducing digital contents into a joint decryption and playback of the program.

再者,可将一部分划分并加密的数字内容配置在再现软件中,并以某种不同于该再现软件的文件格式存贮其它数字内容。 Further, a portion of the divided and encrypted digital contents can be arranged in the reproduction software, and other digital content stored in something other than the reproduction software file formats.

而且,由于出租商的服务器210具有一张下载给特定成员100计算机110的数字内容表(贮存在存储器220内),所以可将下载给要求再次下载该数字内容的成员100计算机110的数字内容与该表内描述的数字内容作比较。 Further, since the rental store server 210 has a digital table of contents downloaded to a particular computer 110 members 100 (stored in the memory 220), the digital content may be downloaded to the download of the digital contents again member 100 and computer 110 description of the figures in the table for comparison. 只有在两者相同时,才能下载新的数字内容,当两者不同时,则通知用户的计算机。 Only two are the same, to download new digital content, when the two are not the same time, inform the user of the computer.

这样,当某一成员100复制了另一成员100下载的数字内容时,该表描述的数字内容肯定不同于某一成员100的计算机中下载的数字内容,从而有效地防止该数字内容的非法复制活动。 Thus, when a member 100 to copy digital content downloading another member 100, the digital contents of the table describes the digital content is certainly different from a member computer 100 downloads, thereby effectively preventing illegal copying of the digital content activity.

另外,可将再现软件装入成员110的多台计算机,此时希望预先设定成员100可能安装的计算机台数。 Further, the software may be loaded into the reproducing multiple computers member 110, in which case a predetermined number of desired members 100 computer units may be installed.

如此构成后,即便某一成员100拥有多台计算机110,即比如一台台式计算机和一台便携式计算机(包括PDA、移动电话等),该数字内容只能下载一次,从用户友善的观点来看这是合适的。 After such a configuration, even if a member has more than 100 110 computers, that is, such as a desktop computer and a laptop computer (including PDA, mobile phone, etc.), the digital content can only be downloaded once from the point of view of the user-friendly this is appropriate.

同时,当改变用户成员100计算机110的系统时钟时,即使租期实际上已过了,也不能执行删除程序,从而非法地租用该数字内容。 Meanwhile, when changing the user computer system 100 members 110 of the clock, even if the lease is actually passed, it can not delete the program, thereby illegally renting the digital content.

为解决上述问题,在计算机110每次访问服务器210时,可将计算机110的系统时钟显示的时间与服务器210的系统时钟显示的时间作一比较,二者不同时,可按服务器210的系统时钟显示的时间修正计算机110的系统时钟显示的时间。 To solve the above problem, each time the computer 110 to access the server 210, computer 110 may be a display system clock and the system clock time server 210 to make a comparison of the display, not both, according to the system clock server 210 time clock correction time the computer system 110 is displayed on the display.

这样,可以防止成员100自己改写计算机110的系统时钟的非法租用活动。 This prevents the members 100 to rewrite their own illegal activities rental system clock of the computer 110.

此时,当差值超出成员100计算机110的系统时钟显示的时间与服务器210的系统时钟之间预定的允差时,至少要通知成员100计算机110。 At this time, when the time difference exceeds a member computer 100 and the server 210 of the system clock between a predetermined tolerance of the system clock 110 when the display, to inform the members of at least 110 100 computer.

上述允差较佳地用天数设置,因为租期是用天数设置的,从而成员100计算机110的系统时钟即使变化在24小时内的某一界限,也认为其伤害很小。 Preferably, the above-described tolerance set by the number of days since the lease is set number of days, the computer system clock 100 so that member 110 is a certain limit even change within 24 hours, but also that the damage is very small. 然而,该允差并不限于以天数设置。 However, this tolerance is not limited to the number of days.

此外,在通知成员100计算机110方面,除了客气警告如“你的系统时钟走时不准”以外,警告通知不允许进一步下载数字内容。 In addition, in terms of 110 100 computer to inform the members, in addition to polite warning such as "No system clock when you go" outside, no further warning notification to download digital content.

发明效果本发明的数字内容租用方法包括:把能再现预定格式数字内容的再现软件装入用户计算机的步骤,把再现软件能再现的数字内容下载给计算机的步骤,自数字内容下载给计算机起测量时间,并在过了预定时间删除计算机里的数字内容的步骤。 Effect of the Invention The method of renting the digital contents of the present invention comprises: the software capable of reproducing a predetermined format of the digital content loading step the user computer, the software can reproduce the digital content downloaded to the reproducing step of the computer, since the digital content downloaded to a computer to measure time, and after a predetermined time to remove the computer in digital content steps. 再现软件内配置了测量时间的程序和删除下载的数字内容的程序。 Program measures time program and delete the downloaded digital content in the reproduction of the software configuration.

因此,根据该数字内容租用方法,租用数字内容不必到店里。 Thus, the method according to the digital content rental, rent to store digital content does not have to. 而且,不会出现所需的数字内容因被别人租去而租不到的情况。 Moreover, the case may require digital content having been rented to someone else and not rent does not occur. 再者,由于设置了自数字内容下载给计算机起测量时间并在过了预定时间删除计算机里数字内容的步骤,而且再现软件中配置了测量时间的程序和删除数字内容的程序,可以减少要发送给成员计算机的数据量和发送所需的时间。 Further, since the step to download the digital content from the computer to the measurement time and a predetermined time passes delete the computer digital content, and reproducing software program in which the measurement time of the program, and deleting the digital content can be reduced to be transmitted time the amount of data to a computer and send members required.

而且,另一种数字内容租用方法包括:把能再现预定格式数字内容的再现软件装入用户计算机的步骤,把该再现软件能再现的数字内容下载给该计算机的步骤,计数再现软件再现数字内容的次数,并在过了预定次数删除计算机里的数字内容的步骤。 Furthermore, another digital content rental method comprising: a reproduction software capable of reproducing a predetermined format of the digital content loading step the user computer, the software, the reproduction can reproduce the digital content downloaded to the step of the computer, the digital contents reproducing software playback count number, and after a predetermined number of times to delete the computer's digital content steps. 再现软件内配置了计数次数的程序和删除数字内容的程序。 The viewer software program is configured to count the number of digital content and a program to delete.

这种数字内容租用方法也具有与上述相同的效果。 The method of renting such digital content has the same effect as described above. 此外,由于引入了再现次数的概念,能更自由地调整观看数字内容的时间。 Moreover, the introduction of the concept of reproduction times, more freedom to adjust the viewing time of the digital content.

此外,若在下载数字内容时设置预定的时间或次数,用户能方便地根据其生活规律调整观看时间。 Further, when the set number of times or a predetermined time when downloading digital content, the user can easily adjust the viewing time according to their patterns of life.
